It is widely used in various electrical circuits and plays the role of connecting or disconnecting current or signals. An electronic connector is a motor system and a device for transmitting electronic signals. It can provide a separable interface to connect two sub-electronic systems. Simply put, it is a component used to complete the electrical connection between circuits or electronic machines, such as power plugs and sockets, IC pins, telephone line plugs, etc. As electronic connectors become more miniaturized and automated, they are increasingly widely used in the electronics industry. Electronic connectors are generally made by injection molding machines, and clamping devices are generally used in the injection molding process to assist in material removal.

[0029] How this utility works:

[0030] Refer to the instruction manual Figure 1-4When in use, the staff first places the base 121 on the workbench, and then the staff rotates the handle 127 in the forward direction, so that the handle 127 can drive the roller 124 to rotate in the forward direction, so that the roller 124 can drive the two driving bevel gears 125 to rotate in the forward direction synchronously, and the two driving bevel gears 125 are meshed with the adjacent driven bevel gears 126 when rotating, so that the two driven bevel gears 126 can be driven to rotate in the forward direction synchronously, so that the two driven bevel gears 126 drive the two driving screws 129 to rotate in the forward direction synchronously, so that the two driving screws 129 can jointly drive the driving plate 122 to move downward, so that the driving plate 122 can quickly push the three suction cups 128 out of the inner cavity of the base 121.

When the molding mold contacts the workbench, the staff starts the drive motor 11 through an external power supply, so that the drive motor 11 drives the threaded rod 17 to rotate in the opposite direction, which can drive the two clamping plates 10 to move to both sides and separate from the molding mold, so that it can be quickly placed on the workbench for processing.Repeat the above operation to take materials and reprocess more molding dies. The above is the entire working process of the utility model.
